I tested 16/44 PCM through HibyMusic on my LG V35 and see the same effect
@5h0l3e5 reported - it goes through the mixer and comes out as 48 kHz. I haven't tested the V30, V40, V50, etc., but I'd expect to see the same effect. I've not tested other sample rates either because 1) 44 kHz is the most important and if it gets that wrong it's game over and 2) I'm lazy
Couple of other thoughts.
About all these other apps that people want to test to see if it re-samples or not.... Can you hear the difference? To me, the resampling artifacts are only audible on certain tracks and with certain headphones. If you're listening with a pair of HD800s for example, you probably don't need to worry about any of this. If you can't hear the effect, just enjoy the music. There's nothing like a good global pandemic to put things in perspective
What are peoples' thoughts on the V60? Its specs and battery life look great and maybe the 2nd screen would be handy for Fortnite or pubg, but this thing's huge. Is it just me or does anybody else think it's a shame LG aren't making phones the size of the V30 or V35 anymore? (Even though the Velvet series has a 3.5 mm socket, rumors are it won't have the quad DAC.)
